Abstract
The invention provides a double-rotor linear compressor. The double-rotor linear compressor comprises a shell, an air cylinder, a piston, a stator iron core, a winding coil, rotors, permanent magnets, end covers, a linear bearing, resonance springs, and an adjustment nut. The stator iron core has a dumbbell shape and is formed by laminating silicon steel sheets in an axial radiation mode. A recessed part of the outer wall of the iron core winds the winding coil in a circumferential direction so as to form a concentrated winding; a protruded part of the outer wall of the iron core is fixedly connected with the inner wall of the shell; and one end cover is provided with the linear bearing, the resonance spring is arranged inside and outside one end cover respectively, and the other end cover is provided with an air inlet valve and an air discharge valve. The end parts of the inner sides of the two rotors are provided with annular grooves, annular permanent magnets are adhered and embedded into the grooves, cylindrical permanent magnets are adhered and embedded into the outer walls of the inner sides of the two rotors, the rotors are fixedly connected with the piston shaft, and a piston and a shaft are integrated. The piston shaft passes through an end cover spring and the linear bearing and is connected with the adjusting nut, and the stroke of the rotors is adjusted through the adjusting nut. The rotors do linear reciprocating motion by taking the air cylinder and the linear bearing as the supporting points, and the end parts of the inner sides of the rotors have the same polarity as the permanent magnets on the outer walls of the inner sides. When alternating current is led to the winding coil, the magnetic field of a stator and the magnetic field of rotor permanent magnets interact, and attractive force and pushing force to the rotors at two ends can be generated. The rotors are pushed to do linear reciprocating motion in an axial direction, and the double-rotor linear compressor is high in efficiency, light in weight, and compact in a structure and has a wide application range.
